3D Modeling Part 2

I am also starting to create several of the assets around my main prop (Truck). I've started modelling the tires in order to see how many polys I will use in creating the other props within the scene so that I can limit myself to how many poly I will use on the truck although I am giving myself a maximum of 2000tris for the other props in the environment which means I have a maximum of 8000tris for the truck.
Below is the start of my tire which is very low poly as within my reference images I am going to use at least 10-15 tires although when in the unreal engine I may be able to remove some of the back facing polys which will not be seen in order to reduce polys.

3D Modeling Part 2

Found another refence image in which I can see the front of the vechile. to create the bonet I used a sphere and halfed it and took of the bottom half. then extruded the back edges and raised it a bit looking at how the bonet of the truck is. I then created a flat face and position it to roughly where the end of the headlights is and then created a cyclinder to get the shape of the arch.
